Not sure where you get the CNC from! IMHO the Rolex* looks too glossy and shiny in comparison, everything about it says 'look at me' even the new ceramic bezel gleams. It also weighs a ton on the wrist because it's a big chunk of steel. I'm not anti-Rolex at all, I love my Explorer but it's a lot more discreet.
The Sub is the total opposite to the Pelagos, subtle, understated, considered, light to wear but still has presence. But I say this from having worn both. Before you make up your mind I'd suggest comparing them side by side and if you can spending a day (or at least a few hours) wearing each. You really can't make an informed decision from a pic on the interwebz ;)
*Am talking about the latest 'ceramic bezel' edition of the Submariner, not Ordinata's lovely Lolex ;)
